Wanted to give an update on this. All my issues (odd latency, slow
throughput, etc) went away when I switched from the in-kernel e1000e
driver to Intel's NAPI driver.
That is, I compiled e1000e driver 3.8.7-NAPI from
https://sourceforge.net/projects/e1000/files/e1000e%20stable/ ,
instead of using the mainline e1000e driver from kernel 5.4.75 in
openwrt dev.
After switching to the Intel driver, my internet has been rock solid.
My NIC from lspci:
01:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection
This is the "Intel EXPI9301CT Desktop Adapter Gigabit" from newegg. I
bought it figuring it would have good linux support. *grin*
And it does, but not with the mainline driver it seems. The in-kernel
driver doesn't (I assume) support NAPI -- so very possibly this is due
to the NAPI support in the out-of-tree driver (vs being an issue with
the driver itself)
